I agree with what Dom said.
I disagree with different prices for different programs. If it were me, I’d be pissed off to find out that I paid a higher price for the same service as another program.
Everyone should be charged the same price for the same service. I can see prices being different if someone signs a longer contract and/or prepays for a longer period. But otherwise the price should be the same for program A as it is for program B. Period.
